APPARATUS FOR MAKING SULFURIC ACID# Application filed May 28,

In making sulfuric acid it has long'beenl common to use steam inthe lea'den chambers. Usually several steam jets` 'deliver into'the chambers', but the production of steam adds to the expense loffacid` making. It has been proposed to use sprays or' water instead of steam, but without entire success, chiefly owing to the fact that the chambers are not high enough, so that the atomized Water was not vaporized but mixed with the acid,` thereby`diluting it, besides aiding yin the formation of nitrous compounds which attack the lead wall of the chamber. It has been proposed to overcome these'diliicultie'sby increasing the height-of the chamber, but thisl is open to serious objections. The cost of the chambers is greatly increased and eX- erience has shown that they ought-not to e higher than from 5-7 meters to get the best results.

According to my invention I arrange on]y different cones or cylinders, into the top o each of which a water spraying nozzle livers. The height and diameter of th e cones or cylinders are so `proportioned tha a the upper part of the leaden chamber sever? conical jet of atomized Water is, under or i-l.. nary clrcumstances, entu'ely vaporlzed fbe.

fore reaching the bottom of thechambe but to prevent any drops of Water from mil lng the acid xn the bottom of the chambr,

. all the water should not bey converted in o steam, I arrange under each atomizera.'A suitable uater receptacle. l f

As hitherto used the atomizer nozzles'are velv liable to become useless by reason" o f the small openings therein being soon closed by impurities, even if `filtered Water isieulplyed. Gf course such nozzles could be frequylently inspected and cleaned. but this is very inconvenient. so that many manufacturiers have rejected the new process. or atomii/,ed water method. aud have returned to the old l method o f using steam. By my apparatus,

' eferring to su furic acid chamber supported in a suit-` ab e framework b. c represents #the top of 'thd chamber in which are cut a number of cirpular holes n arranged in any suitable manner, centrally across the top of the chamber. Ouereacl of the holes n is a cene d having a leald lining, the bottom of the couebeing secugr'ed to the top of the leaden chamber by nected with the tank f and passes out i the surplus Water. This-pipe -is provided with a goose neck o. It represents the level of the acid in the bottom of the chamber. One of these tanks or receptacles f may be used under each cone or the tank may run thewhole length of the chamber to catch the unvaporized water from all the cones. Of course the parts f, g and @I must be made of acid resisting material.
